Thank you for the support. Luckily it seems that my father handled the last dose of BCG pretty well (with only minimal side effects).
I think the 1st time, the reason for all those side effects is because my father held the BCG for ... 5 hours.
The doctor told him he should hold it in for "at least" 2 hours. So my father, thinking the longer the better, held it in for 5 hours. I blame myself, I wasn't very involved at that point, if I was I would have done more research and given my father better instructions.
My question now is, could the 1st time done any permanent damage to my father's bladder? I asked a few doctors, they have differing opinions. The doctor that is actually seeing my father said no, but I feel he is trying to cover any blame he might have.
I've tried Googling it, but turns out there aren't really a lot of other people that held BCG longer than 2 hours.
